Bewitched (1964) : 8x4

Next Stop, Italy! The Stephens enjoy their vacation in a hotel overlooking the famous Leaning Tower of Pisa. Of course, Esmerelda pops in due to a lack of confidence. Esmerelda reveals that she made the tower lean by mistake when she was engaged to the builder. So Esmerelda takes it upon herself to right the wrong...by actually straightening the Leaning Tower of Pisa! The town totally freaks out when the famous tower is straightened correctly, and Esmerelda cannot remember what happened to make the Tower lean in the first place! A trip back in time helps her to remember. It seems that she tried to twitch up a tower sandwich for the builder and to make it lean, thus making the Tower lean again.
